I have friends who just love their cutting machines but they just don't appeal to me. I figure it's just a style difference. Recently I've been working with some precut squares and found it just didn't appeal to me on several levels, for one I've been working with WoF, strip piecing and rulers for so long I just don't think in terms of units, I think in terms of strips. One of the ladies I quilt with uses a sewing machine and chain stitches but she does cut squares and pieces them together where I cut strips, sew those together and then subcut them into combined square units. She actually doesn't like the cutters either but for her it's a size commitment issue that she doesn't want to make. Space is a consideration for me as well.
Now... if I did EPP hexagons or any hexes or tumblers or some other shapes like that, I'd probably like a cutting machine very much. It's just not my thing. The fancy ones that do programmable shapes, super cool but I don't applique either.
